In astrophysical turbulent flows radiative transport can be affected by
turbulence.
This effect is different for optically
thick and optically thin regimes of the radiative transport.
For optically thick regime, the mean free path of photons is much smaller
in comparison with the typical scales of the flow.
In the opposite case, i.e., for optically thin regime, the mean free path of photons is much
larger than the fluid motion scales, so the photons propagate over
large distances before they are absorbed and re-emitted
again [1]}, [2]}, [3]}, [4]}, [5]}.
